Synchrotron X-ray photoelectron As 3d and S 2p spectra of gersdorffite reveal that the surface monolayer includes two types of surface anionic species, As-S dimers and As-S multimers (probably tetramers), the latter being the product of a polymeric s

The reactivity of arsenopyrite (FeAsS) fractured surfaces toward oxygen was studied using synchrotron radiation excited photoelectron spectroscopy (SXPS). The spectra of the pristine surface provide evidence of different As and S surface sites. Signa

The paper presents new results on the adsorption of 2-mercaptobenzothiazole (MBT) and 2-mercaptobenzoxazole (MBO) on galena (PbS) and pyrite (FeS 2 ). Adsorption of MBT and MBO on galena and pyrite surfaces from 10 −5 M aqueous solution results in

The redox reactions of 2-mercaptobenzoxazole (MBO) have been investigated by cyclic voltammetry at glassy carbon electrodes in aqueous solution. Four anodic and three cathodic processes could be identified. A more detailed analysis of the oxidation p

Synchrotron excited and conventional X-ray photoelectron spectroscopy has been used to study the initial oxidation of fractured pyrite surfaces in air. The dramatically enhanced surface sensitivity obtained with synchrotron radiation allowed us to fo

Synchrotron-radiation-excited photoelectron spectroscopy was used to monitor sulfur chemical states on fractured pyrite surfaces reacted with atmospheric gases. The results demonstrate that there are at least three distinct states at the pyrite surfa
